Paging with Direct Channel Access
With this feature, direct channel access is granted to the telephone user immediately after paging the
mobile. The telephone user has access to the channel for a certain time (the direct access duration). At
the end of that time, the PL1877A disconnects the telephone user. The direct access duration can be
extended to the normal, overall access duration by:
• Programming the PL1877A to extend the direct access duration if mobile carrier is detected; or
• Requiring reception of a wildcard access code that includes the paged mobile's capcode or user ID
digits.
For example, suppose the PL1877A is operating in single-mode paging and has paged a mobile with a 2-
tone capcode of 023. The telephone user has been granted direct channel access. If the mobile enters a
wildcard access code that includes some or all of the digits 0, 2, or 3, the time allotted for direct access is
extended to the overall access duration.
Suppose the PL1877A is operating in multi-mode paging and has just paged a mobile with a user ID of
56. The telephone user has been granted direct channel access. If the mobile user enters a wildcard
access code that includes the digits 5 and 6 the time allotted for direct access is extended to the overall
access duration.
